Our master bed room and east side of our home is on a seperate AC unit. During the day we are not in that area of our home. So, we leave the AC off and turn it back on a couple of hours before we go to bed. We set the thermostat for 78 when sleeping. Would it be more efficient to let that AC run during the day with the thermostat set for upper 80s, versus starting it a few hours prior to going to bed. Yesterday evening the temp on the Master bedroom thermostat was 91 when I turned on that AC. Seemed like that unit ran for most of the night, but did finally shut itself down.
